Yet in the modern society where so much deals with authentication email messages have become quite bloated with overhead that deals with authenticity of the message / message sender.<br> <br> What happens when a low-speed network is needed to complete the delivery? Will the message delivery be delayed because of the overhead. What is the solution?<br> <br> What prevents spread spectrum technology from being used on High Frequencies (HF)? There's some work being done on UHF (70cm) that will help in regional delivery of messages. What will it take to make this technology more wide-spread? <br> <br> <br> </font></div> </div> </div> ResourceOnehttp://www.blogger.com/profile/02758790305630105325noreply@blogger.comtag:blogger.com,1999:blog-5017637753597678217.post-42003681431665713172014-02-22T11:36:00.000-08:002014-07-29T20:32:19.660-07:00Midian Electronics : PARTI-1 PA Radio/Telephone Interface<br /><br /><br /><table border="0" cellpadding="0" cellspacing="0" style="width: 600px;"> <tbody><tr> <td colspan="1" rowspan="1" width="100%"><table border="0" cellpadding="0" cellspacing="0" id="content_LETTER.BLOCK1" style="width: 100%px;"> <tbody><tr> <td align="center" colspan="1" rowspan="1" style="color: black; text-align: center;" valign="bottom"><div align="center" style="text-align: center;"><a href="http://4.bp.blogspot.com/-mCS8-2W4VGE/Uwj781QyWJI/AAAAAAAAAD0/13amnmznc00/s1600/ACCOUNT.IMAGE-714974.12"><img alt="" border="0" src="http://4.bp.blogspot.com/-mCS8-2W4VGE/Uwj781QyWJI/AAAAAAAAAD0/13amnmznc00/s320/ACCOUNT.IMAGE-714974.12" id="BLOGGER_PHOTO_ID_5983309127469914258" /></a></div></td> </tr></tbody> </table><table bgcolor="#ffffff" border="0" cellpadding="5" cellspacing="0" id="content_LETTER.BLOCK2" style="background-color: white; margin-bottom: 6px; margin-top: 6px; width: 100%px;"> <tbody><tr> <td align="left" colspan="1" rowspan="1" style="color: black; font-family: Verdana,Geneva,Arial,Helvetica,sans-serif; font-size: 10pt; text-align: left;"><br /><span style="color: black; font-family: Verdana,Geneva,Arial,Helvetica,sans-serif; font-size: 10pt;"><b>PARTI-1 Public Address Radio/Telephone Interface&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </b></span></td> </tr></tbody> </table></td> </tr><tr> <td colspan="1" height="15" rowspan="1"><br /></td> </tr><tr> <td colspan="1" rowspan="1" width="100%"><table bgcolor="#ffffff" border="0" cellpadding="5" cellspacing="0" id="content_LETTER.BLOCK3" style="background-color: white; margin-bottom: 6px; margin-top: 6px; width: 100%px;"> <tbody><tr> <td align="left" colspan="1" rowspan="1" style="color: black; font-family: Verdana,Geneva,Arial,Helvetica,sans-serif; font-size: 10pt;"><div style="margin-bottom: 0px; margin-top: 0px;"><span style="color: blue;">In a nutshell the PARTI-1 allows access to an existing <span style="color: blue;">Public Address system&nbsp;</span>via&nbsp;two-way radio with an option for access via cell, landline or&nbsp;VoIP telephones.

Thus providing additional communications coverage area.<br /><br /><b>What will it be used for:</b><br /><br />Provide additional communications coverage area; also can be used to augment communications resources in emergency situations and special events.<br /><br /><b>How will it connect to other stations:</b><br /><br />Depending on the complexity of the Remote Base (and the amount of funds available) the ideal situation would be to have a combination of RF and Internet backhaul capabilities. If Internet access is available this would be the ideal method for connectivity. Once again if funds are available use of Satellite Internet services would provide some additional remote accessibility.<br />When using RF backhaul capabilities there are number of methods that can prove to be beneficial. When possible consider VHF Links and for full-duplex A VHF / UHF combination. We cannot forget about the flexibility of HSMM on 2.4, 3.3, 5.8 GHz and even 902 MHz has some promising potential.<br /><a href="https://www.blogger.com/blogger.g?blogID=5017637753597678217" name="more"></a><br /><br />Can HF be considered a viable extension of the Remote Base Link? Depends on the mission objective. Looking back to some of the applications in the past couple of years where HF Remote Base Links have been used as a method to receive emergency traffic from distant locations out of normal range of EOC there may be some practical usage for HF.<br /><br />The way the Amateur Radio licensing is set up it is rather tough to test a station in a non-emergency setting. Especially for those holding a Technician Class license. There are some that have taken the test for the General and Extra class license and passed the test yet don’t have a clue about the technology that they were tested on. It appears that some don’t really care about the technology just the fact that they can now “talk voice on HF.” In some instances voice on HF will not be the best approach for getting the necessary information from those that have it to those that need it.<br /><br /><i>Okay back to the Remote Base chatter …</i><br /><br /><i>So what do we need to create a Remote Base?</i><br /><br /><b>What do we need to create a Remote Base:</b><br />Determine the type of terrain in which the Remote Base will operate; is it urban, rural, forested, hilly, mountains, etc.<br /><br /><b>What resources are available;</b><br /><ul><li>Internet; Dial-up, Broadband, HSMM, Satellite;</li><li>RF Equipment – HF, VHF, UHF, Microwave;</li><li>Power – Grid, Solar, Wind, Battery, Generator</li><li>Antenna Structure – Building, Tower, Mast;</li></ul><b>What is the distance that needs to be covered between the Remote Base and Base / Repeater Site:</b><br /><br />Will the distance require additional enhancements via extenders, cross-band repeaters, etc:<br />Once the above information is available we can start working on creating the actual Remote BaseResourceOnehttp://www.blogger.com/profile/02758790305630105325noreply@blogger.com
